Variants§
GenericParamsFromOuterItem(Res<NodeId>, HasGenericParams)
Error E0401: can’t use type or const parameters from outer item.
NameAlreadyUsedInParameterList(Symbol, Span)
Error E0403: the name is already used for a type or const parameter in this generic parameter list.
MethodNotMemberOfTrait(Ident, String, Option<Symbol>)
Error E0407: method is not a member of trait.
TypeNotMemberOfTrait(Ident, String, Option<Symbol>)
Error E0437: type is not a member of trait.
ConstNotMemberOfTrait(Ident, String, Option<Symbol>)
Error E0438: const is not a member of trait.
VariableNotBoundInPattern(BindingError, ParentScope<'a>)
Error E0408: variable {}
is not bound in all patterns.
VariableBoundWithDifferentMode(Symbol, Span)
Error E0409: variable {}
is bound in inconsistent ways within the same match arm.
IdentifierBoundMoreThanOnceInParameterList(Symbol)
Error E0415: identifier is bound more than once in this parameter list.
IdentifierBoundMoreThanOnceInSamePattern(Symbol)
Error E0416: identifier is bound more than once in the same pattern.
UndeclaredLabel
Error E0426: use of undeclared label.
SelfImportsOnlyAllowedWithin
Error E0429: self
imports are only allowed within a { }
list.
SelfImportCanOnlyAppearOnceInTheList
Error E0430: self
import can only appear once in the list.
SelfImportOnlyInImportListWithNonEmptyPrefix
Error E0431: self
import can only appear in an import list with a non-empty prefix.
FailedToResolve
Fields
module: Option<ModuleOrUniformRoot<'a>>
Error E0433: failed to resolve.
CannotCaptureDynamicEnvironmentInFnItem
Error E0434: can’t capture dynamic environment in a fn item.
AttemptToUseNonConstantValueInConstant(Ident, &'static str, &'static str)
Error E0435: attempt to use a non-constant value in a constant.
BindingShadowsSomethingUnacceptable
Fields
shadowing_binding: PatternSource
Error E0530: X
bindings cannot shadow Y
s.
ForwardDeclaredGenericParam
Error E0128: generic parameters with a default cannot use forward-declared identifiers.
ParamInTyOfConstParam
ERROR E0770: the type of const parameters must not depend on other generic parameters.
ParamInNonTrivialAnonConst
generic parameters must not be used inside const evaluations.
This error is only emitted when using min_const_generics
.
ParamInEnumDiscriminant
generic parameters must not be used inside enum discriminants.
This error is emitted even with generic_const_exprs
.
SelfInGenericParamDefault
Error E0735: generic parameters with a default cannot use Self
UnreachableLabel
Error E0767: use of unreachable label
TraitImplMismatch
Error E0323, E0324, E0325: mismatch between trait item and impl item.
TraitImplDuplicate
Error E0201: multiple impl items for the same trait item.
InvalidAsmSym
Inline asm sym
operand must refer to a fn
or static
.
LowercaseSelf
self
used instead of Self
in a generic parameter
